I was just playing with my <5mW $5 pointer. I was pointing it at my ceiling which was like 5-6 feet away from me. I noticed that there were these blue lines that were bending when I would move the pointer up and down and in circles. I swear I'm not a pot head and as far as I know I have 20/20 vision. I honestly think these lines were in my eyes or brain and were reacting to the light. Can anyone help me figure this one out? I know it's weird but it's freaking me out.
